Is millisecond resolution "good enough" for mail synchronization?
Or maybe even seconds is sufficient...
When syncing mail across machines/devices/reboots, using the
system clock seems required (anybody syncing mail also uses
NTP, right?).
While Time::HiRes allows access to .tv_nsec for some APIs;
Time::HiRes::stat converts it to a double-precision float
(NV/Numeric Value in perlguts-speak). That's not enough for
microsecond accuracy, even; and of course I don't think most
kernels or HW is actually accurate down to the nanosecond level.
